Automatic White-Balance (AWB) for a Camera System - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240292115 titled 'Automatic White-Balance (AWB) for a Camera System
- Simplified Explanation:**
This patent application describes techniques and apparatuses for automatic white balance for a camera system. The system uses a precursor image to detect faces, determine tone, and adjust white balance accordingly.
- Key Features and Innovation:**
- Utilizes a precursor image to detect faces and determine tone
- Retrieves tonal data based on a group of images with the same face
- Determines white balance based on the difference in tone
- Adjusts camera settings for improved tone capture
- Potential Applications:**
This technology can be applied in various industries such as photography, videography, surveillance systems, and facial recognition software.
- Problems Solved:**
- Inaccurate white balance in images with different tones
- Difficulty in adjusting camera settings manually for optimal tone capture
- Benefits:**
- Improved image quality with accurate white balance
- Simplified process for adjusting camera settings
- Enhanced facial recognition capabilities
- Commercial Applications:**
Automatic white balance technology can be used in digital cameras, smartphones, security cameras, and video conferencing systems to enhance image quality and facial recognition accuracy.
- Questions about Automatic White Balance:**
1. How does automatic white balance technology improve image quality?
- Automatic white balance technology adjusts camera settings based on detected faces to ensure accurate color representation.
2. What are the potential drawbacks of relying on automatic white balance in a camera system?
- Automatic white balance may not always accurately adjust settings for unique lighting conditions, leading to color inaccuracies in images.
Original Abstract Submitted
this document describes techniques and apparatuses for automatic white-balance for a camera system. the techniques and apparatuses utilize a precursor image to detect one or more detected faces and determine a tone. the camera system retrieves tonal data based on a group of images determined to contain a same face as the detected face. based on this tonal data, a difference in white balance is determined based on the difference in tone of the detected face within the precursor image and the associated tonal data. camera settings are adjusted based on the difference in white balance to enable capture of an image having an improved tone.
